Using this kit is super easy. First, take out the artboard you want to color and the color guide. The guide will tell you which color to use for each number on the artboard. Then, pick up the appropriate paint marker and start coloring. Remember, the markers are double - ended, so you have more colors to choose from. When you're done coloring, place the artboard on one of the stands to display it. As for maintenance, keep the markers capped when not in use to prevent them from drying out. Also, store the kit in a cool, dry place. And since the art boards are non - toxic, it's safe for kids, but always make sure they don't put the markers in their mouths.
